Benefits of technology
[0010]The present invention has been made in view of the above-mentioned problems and an object of the present invention is to provide a technique of displaying auxiliary lines so as to make it easy to catch the sense of depth when displaying a stereoscopic image using radiological images.
[0016]According to the above aspects of the present invention, auxiliary lines which are made up of a plurality of grids appearing to be arranged in the depth direction are added on the plurality of radiological images so as to be stereoscopically viewed in accordance with a sense of depth of the stereoscopic image so that at least one of the colors, thicknesses, kinds, luminance levels, blinking methods, and directions of the lines of grids adjacent in the depth direction are different. Thus, the grids adjacent in the depth direction can be recognized in a discriminated manner. As a result, by using the auxiliary lines when making diagnosis using stereoscopic images, a stereoscopic effect of structures included in a stereoscopic image can be figured out easily.
Problems solved by technology
Thus, when a stereoscopic image is displayed using radiological images, since structures are displayed stereoscopically with a stereoscopic effect so as to stay afloat in a space, it is difficult to catch the sense of depth of structures in the stereoscopic radiological image.
However, it is difficult to match the sense of depth of the 3D cursor so as to be identical to the sense of depth of a region of interest such as a lesion in a stereoscopic image.
However, since a plurality of structures is included in a radiological image so as to overlap each other in the depth direction, it is very difficult to calculate corresponding points at the same sense of depth.
Thus, it is difficult to apply the technique which uses the contour lines representing the same depth as disclosed in JP2006-271739A to a stereoscopic image of radiological images.
Moreover, in the technique disclosed in JP2009-053147A, since the grid lines are displayed with the same lines regardless of a sense of depth, when the technique is applied to a stereoscopic image using radiological images, it is difficult to discriminate which grid line represents which depth.
Thus, it is difficult to make accurate diagnosis.

Embodiment Construction
[0025]Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic configuration view of a radiological image radiographing apparatus to which a radiological image displaying apparatus according to an embodiment of the present invention is applied. A radiological image radiographing apparatus 1 according to this embodiment radiographs a breast M from different radiographing directions to acquire a plurality of radiological images in order to generate a stereoscopic image for stereoscopic viewing of a radiological breast image. As shown in FIG. 1, the radiological image radiographing apparatus 1 includes a radiographing unit 10 having an image acquisition unit (not shown), a computer 2 connected to the radiographing unit 10, a monitor 3 connected to the computer 2, and an input unit 4.
[0026]The radiographing unit 10 includes a base 11, a rotation shaft 12 that is movable in the vertical direction (Z direction...

Provided is a technique of displaying auxiliary lines so as to make it easy to catch the sense of depth when displaying a stereoscopic image using radiological images. Auxiliary lines are added on two radiological images for displaying a stereoscopic image, respectively. The auxiliary lines are made up of a plurality of grids appearing to be arranged in the depth direction, and the display modes of adjacent grids are different. For example, at least one of the colors, thicknesses, kinds, luminance levels, blinking methods, and directions of the lines of the adjacent grids are different.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a radiological image displaying apparatus and method for displaying stereoscopic images of a subject.[0003]2. Description of the Related Art[0004]In the related art, it is known that stereoscopic viewing can be realized using parallax by displaying a plurality of images in combination. Such an image (hereinafter referred to as a stereoscopic image or a 3D image) that can be viewed stereoscopically is displayed based on a plurality of images having parallaxes acquired by photographing the same subject from different directions.[0005]Various methods for making it easy to figure out the stereoscopic effect of structures included in an image when a stereoscopic image is displayed have been proposed. For example, according to a technique disclosed in JP2006-271739A, corresponding points in two eye-fundus images acquired by photographing the eye fundus from different direction, for displaying ...
